To all 'wkomz't may concern:

Be it known that I, V'Io'ron SCHLEYER, a citizen of theUnited States,residing at Anderson, in the county of Madison and State of Indiana,have invented a new and useful Sand-Protected Bearing for Deep-WellPumps, of which the following is a specification.

i .111 the operation of deep-well pumps-in which a shaft extends downinto the well to 0 erate a pump at the lower end of such s aft muchtrouble is caused by sand and dirt in the bearings, as the water oftencarries with it great masses of sand and dirt, which rise with thewaterduring pump operation and settle downward when the pump stops. Thisoften results in the do- I struction of the bearings and of the shaft atthe bearings in a very short time, requirin replacements at greatexpense.

t'is the object ofmy present invention to produce a sand-protectedbearing, which i will keep out 'thesand and dirt from the section on theline 22 of Fig. 1; Fig. 3

is a transverse section on the line 3--3 of Fig. 1; and Fig. 4 isafragmentary axial section through a modified bearing cap. I Thevertical shaft 10 which operates the pump in the well extends in theusual manner thrbugh the pi e 11 which carries upward the-water discarged from such pump. The shaft is centered within the pipe 11 bybearings 12, to which my invention relates. The bearing 12issupportedby: aspidei "13, having a,circumferential ring14 which is clamped bbolts 15- between the outthe. bearing. portion thereof, maybe ofanywardly exten 'ng lugs. on two rings 16 having pipe-thread mountingson the adjacent ends of two sections of the pipe 11. The center part-ofthe bearing 12, constituting suitable construction, being shown "asformed of an outer sleeve 17 Zwithin'xwhich is a perforated sleeve 18having formed through it suitable perforations, usually staggeredfin.which are located wooden plugs 19 which bear a ainst the surface of theshaft 10 and provide suitable spaces Specification of Letterskatent;Patentrgqfl Jan, 2%, 1922,, I

between them for the passage of water forlubricating the bearing; thiscenter bearing portion is shown of a standard construction,

and may be varied if desiredl.

On each end of the sleeve 17 is screwed a V cap 20. This cap isformedwith an internal sleeve 21 closely fitting the shaft 10, and anexternal sleeve 22 provided"with an annular series of holes 23 overwhich lies a band screen 2-1 set in a suitable circumferential recess inthe'outside surface of the sleeve 22. Between the two sleeves 21 and22is a bafile ring 25 spaced from both sleeves except at the end towardthe bearin sleeve 17 where it joins the sleeve 22. This provides anannular space 26 with which the holes .23 communicate, and an annularspace 27 which communicates around the free end of the baffle ring 25with the space 26 and also communicates-with a space 28 formed withinthe cap 20 at the base of the screw flange29 by which it is attached tothe'sleeve 17 Set in'the s ace. 28, with its outeredge held in a suite1e iecesson the inner face of, the flange 29, is a screen.

30,- which thus lies between the space 27 and the bearin plugs 19. Thustwo screens23 and'30 lie etween the water in the pipe 11 andeac'h endofthe sleeves 17 and 18, and between these two screens and the end'th'ereis aflwinding passageway. Thescreens 23 and 30 are of suitable mesh forthe sand or dirt to encounter. Y

The outer end of each of). sired have a suitable packing 31 held by P souse a v a packing ring 32, asshown in Fig; 4; but

this is. not essential.

The outer end of the cap 20 or of the packingring-32is provided with anannular stepped groove, in which ,fitsa similarly stepped flange 33projectin axially from-a ring 34 clamped to the sha t 10 by a set: screw35. The flange 33 fits within its groove and the sleeve 21 fitsupofi theshaft 10', with sufiicient closeness to prevent the passage therebetween(if sand or dirt carried by the water traveling through the-pipe 11. 7 i

In operation, the sand -.carrying water 'which -.rises through the. pipe11 passes around the outside of the sleeve 17, and across the outersurfaces of the screens'23 at the top and bottom of the bearing. The

lot

pressures atthe two screens 23 are slightl different, and as a resultwater enters throug a proper, formed one of these screens and passes outthrough the other, with a comparatively slow movement through thescreens and the bearing. The watenWhichenters through one screen 23 isfreed-from sand and dirt by such screen and by the comparatively slowmovement of the water through the screen., I This water travels throught e winding passage formed by the spaces 26 and 27 into the s ace 28,

where it encounters the screen 30,- w 'ich removes any remaining sand ordirt. The substantially sand-free water which passes the screen'BO thenpasses through the bearing y the wooden plugs. 19, 'so that such plugsare lubricated by filtered water. After passing the plugs 19, the waterpassesout through the cap" 20 at the other end,"by a path just thereverse of that by which it entered throughthe first cap.

. By reason of the screens andwinding passages provided, it is foundthat the bearin proper is kept substantially free from san and dirt,both durin pump operation and during settling, and t at its life isincreased manytimes. 1

I claim as my invention: v

1. A sand-protected bearing for shafts of deep-well pumps,- comprising abearing sleeve in which the shaft is jofirnaled, and a cap mountedoneach end of the bearing sleeve and provided with a winding passagewayhaving therein one or morescreens and connecting the end of the bearingsleeve with the space outside the bearing,

2. A san -.protected bearing for shafts of dceprwell umps', comprising abearing sleeve inwhich the shaft is journaled, an
